Component-Based Development(CBD) for a system has benefits in terms of improvement of operation and maintenance as well as reduction of development period. But applying the CBD methodology to a system can give rise to difficulties, which are there should be specialists in CBD and domain to apply and there would be a lot of products resulting in the application. To solve the problems, we suggested a suitable methodology in overall process from analysis to implementation after investigating the methodology applicable to small and medium software system by software systems engineering approach. In the application of the suggested methodology to design a ship design process management system, we could confirm the efficiencies of the methodologies.

The structural design of the ships includes two main issues which should be checked carefully, namely the extreme structural response (yielding & buckling) and the fatigue structural response. Even if the corresponding failure modes are fundamentally different, the overall methodologies for their evaluation have many common points. Both issues require application of two main steps: deterministic calculations of hydro-structure interactions for given operating conditions on one side and the statistical post-processing in order to take into account the lifetime operational profile, on the other side. In the case of ultra large ships such as the container ships and in addition to the classical quasi-static type of structural responses the hydroelastic structural response becomes important. This is due to several reasons among which the following are the most important: the increase of the flexibility due to their large dimensions (Lpp close to 400 m) which leads to the lower structural natural frequencies, very large operational speed (> 20 knots) and large bow flare (increased slamming loads). The correct modeling of the hydroelastic ship structural response, and its inclusion into the overall design procedure, is significantly more complex than the evaluation of the quasi static structural response. The present paper gives an overview of the different tools and methods which are used in nowadays practice.

In multi-GHz RF ICs and high-speed digital interfaces, ESD protection devices introduce considerable parasitic capacitance and resistance to inputs and outputs, thereby degrading the RF performance, such as input/output matching, gain, and noise figure. In this paper, the impact of ESD protection devices on the performance of RF ICs is investigated and design methodologies to minimize this impact are discussed. With RF and ESD test results, the 'RF/ESD co-design' method is discussed and compared to the conventional RF ESD protection method which focuses on minimizing the device size.

Innovation is considered as key to ensure continuous advancement and firm progress in any field. Robotics, with no exception, has gained triumph and approval based on its strength to address divers range of applications as well as its capacity to adapt new ways and means to enhance its applicability. The core of novelty in robotics technology is the perpetual curiosity of human beings to imitate natural systems. This desire urges to continuously explore and find new feet. In the past, contemporary machines, in different shapes, sizes and capabilities, were developed that can perform variety of tasks. The major advantage of these developments was the ability to exhibit superior control, strength and repeatability than the corresponding systems they were replicating. However, these systems were rigid and composed of hard an underlying structure, which is a constraint in bringing into being the compliance that exists in natural organisms. Inspiration of achieving such compliance and to take the full advantage of the design scheme of biological systems compelled researchers and scientists to develop systems avoiding conventional rigid structures. This ambition, to produce biological duos, needs soft and more flexible materials and structures to realize innovative robotic systems. This new footpath to craft biological mockups facilitates further to exploit new materials, novel design methodologies and new control techniques. This paper presents an appraisal on such innovative comprehensions, conferring to their design specific importance. This demonstration is potentially useful to prompt the novelty of soft robotics.

Recently, object-oriented techniques have been used more and more for developments of an information system. But, established object-oriented methodologies are hard to express a business process of various abstract degrees in the analysis level and independent components of the system. They have difficulties in developing a large-scale information system of manufacturing industry such as PDM and CIM. This paper proposes an information system development methodology that imports the object-oriented IDEF0 (OOIDEF0) function model in analysis level. This methodology is made up of requirements gathering, system analysis, system design, and implementation. In requirements gathering level, organization diagram and interview technique are used for input data of OOIDEF0 function model. The OOIDEF0 function model, the interface model and function descriptions are made out in analysis level. Information objects and implementation objects are designed on the basis of the OOIDEF0 function model in design level. The database is built and programming is accomplished in implementation level. In order to prove the consistency and efficiency of the proposed methodology, the PDM system for ship production is modeled and prototyped.

Magoksa is famous for its location and history, compared to other traditional temples in Korea, as seen in remarks of Monk Doseon in the Shilla Dynasty: "This temple is where the three disasters can not penetrate." In contrast, the reality is that active researches are not conducted, especially on spatial studies. Magoksa has its unique spatial characteristics that can not be found in other temples of Korea, but the existing studies on Magoksa have focused on style or design aspects, and the research has placed importance in a survey form due to the lack of historical materials. The reason for approaching Zhuangzi's philosophy in studying Magoksa's space is because of the fact that it has affected Zen Buddhism and Pure Land Buddhism of Mahayana Buddhism, and that Magoksa was completed by Monk Bojo of Zen Buddhism. It is expected to deduce the meaningful results due to the reasonal aspects of mutual elements by studying Magoksa as a Buddhism temple through Zhuangzi's philosophy in that context. In pursuit and reinterpretation of the essence of Korean traditional architecture, it is important to consider morphological, stylized aspects, but a variety of methodologies might be also presented in understanding the philosophical aspects.

The practice of using encased steel-concrete columns in medium to high-rise structures has expanded dramatically in recent years. The study evaluates existing methodologies and codal guidelines for estimating the ultimate load-carrying characteristics of concrete-encased short columns experimentally. The present condition of composite column design methods was analyzed using the Egyptian code ECP203-2007, the American Institute of Steel Construction's AISC-LRFD-2010, Eurocode EC-4, the American Concrete Institute's ACI-318-2014, and the British Standard BS-5400-5. According to the codes, the axial load carrying characteristics of both the encased steel and concrete sections was examined. The effect of load-carrying capacities in different forms of encased steel sections on encased steel-concrete columns was studied experimentally. The axial load carrying capacity of twelve concrete-encased columns and four conventional reinforced columns were examined. The conclusion is that the confinement was not taken into account when forecasting the strength and ductility of the encased concrete, resulting in considerable disparities between codal provisions and experimental results. The configuration of the steel section influenced the confining effect. Better confinement is achieved with the laced and battened section than with the infilled steel tube reinforced and conventionally reinforced section. The ECP203-2007 code reported the most conservative results of all the codes used.

This study started from the practical need for a career experience program in the fashion major that is creative and responds to current methodologies. The purpose of this study is to propose a fashion work experience program that combines digital technology and practical experience. The research methods and procedures were as follows: fashion items and wearable devices were selected, the LED smart bag program was developed, and it was executed. A total of 123 students participated in the program, and a satisfaction survey was conducted after observation and oral evaluation. All of the participants completed the LED smart bag processes of design ideation, material selection, production, and styling using an eco-bag (one of the fashion items and as an LED wearable device). As a result of the participants' satisfaction (on a 5-point scale), most items showed a high level of satisfaction of 4.39 points or more. The smart bag program was evaluated to increase interest based on the time allotted and the students' level and to bolster their understanding of, and interest in, the fashion major. Therefore, this study is expected to be baseline to explore diversification of the fashion major work experience program, in order to create interest in the fashion major based on creative convergence competency.

The purpose of this study is to pronounce design trends in contemporary architecture collaborated with new media art concept. Currently, the prevalence of media presence has evolved perspectives on contemporary aesthetics today. To make clear demonstration on the issue, this study categorized new media art's expressional characteristics applied in the contemporary architectural design in conjunction with analytical researches on typologies and expressional characteristics appear in new media art. More specifically, the study selected architects who adopted new media art's expressional characteristics into their works from the year 2000 and performed analytical case studies with regard to the effect of the new media art into their architectural practices. By following methodologies mentioned above, conclusively the study categorized distinct expressional characteristics appears in contemporary architecture as a result of merging with new media art. The characteristics of the new media art appeared in contemporary architecture are categorized into three groups such as the design controlling external environment, the design utilizing web environment and the design participated by users. These observation could be translated that architects could present interactive design between users and building as a result from architect's capability of designing protocols which generate variable forms, colors and patterns in architecture. In particular, architecture utilizing web environment has characteristic capability of configurating user's program in virtual space. Also it is anticipated to suggest new patterns in generating architectural programs and forms. These patterns would not recognize the city merely as an incident or fragmented image but would configurate forms and images constructed by individual notional character. In conclusion, the architecture itself is expected to perform as media to open up opportunities that enables to contribute in expediting interactions among environment, users, and buildings by deviating from perspectives of representation as an object expressed in modernism architecture or as a classical decoration in post-modernism architecture in the past era.
